Vienna businesses now compete in two search environments at once: Google rankings and answers from ChatGPT, Gemini, Perplexity, and Google AI. The agencies below work on that mix through ChatGPT Ads, Answer Engine Optimization (AEO), Generative Engine Optimization (GEO), and related AI search work. Use the entries to compare paid versus organic approaches, local office presence, and whether the fit is B2B, local services, or branded campaigns.
Lengreo treats ChatGPT, Gemini, and Perplexity as part of the same growth system as SEO, paid ads, and outbound. The company publishes AEO, GEO, Geo LLMO, and SaaS AI SEO next to lead generation and website work. They usually connect AI recommendations to meetings and pipeline, not to mention counts alone. Their case material leans toward software, architecture, logistics, and other B2B niches. The agency states that it handles Vienna and other location-dependent AI queries even though the operating footprint is international. Lengreo will feel familiar to teams that sell complex B2B services. The company is a weaker match for local retailers that only need neighborhood citations.

traffic3 built its Vienna offer around the fact that ChatGPT Ads in DACH are still early. The agency checks the offer, feed, and conversion event before spend goes live. They then set thematic ad groups, landing pages, the OpenAI pixel, the Conversions API, and a written rule for when to stop the test. The company treats campaign-level economics as the decision layer because reporting does not show individual chats. Their GEO work covers brands that also want organic citations. The agency works from the 3rd district. They cover Austria, Germany, and Switzerland.

otago added GEO and LLM prompt monitoring after years of SEO, Google Ads, content, social, and programmatic work. The company works from Mariahilfer Straße.

Their account model can keep paid and organic AI work together. otago lists retail, insurance, and other Austrian brands in published results.

SlopeLift puts Austrian AI-visibility studies next to SEO and GEO. The agency also runs SEA, social, programmatic, landing pages, and analytics across DACH and CEE. They treat citation-worthiness in language models as a measurable layer. Their articles explain ChatGPT Ads through content hints and conversation context rather than keyword lists. SlopeLift lists Vienna as the home office. The company also lists Munich, Saarbrücken, Bratislava, and Los Angeles, which matters if the brand sells outside Austria. Their published SEO team is large by local standards. The agency helps multi-market media accounts more than a tightly scoped schema project.

searchads.agency frames ChatGPT Ads through auction mechanics, bidding, budgets, and conversion measurement. The agency starts with a fit check for Austria and Germany. They say some offers and audiences will not convert in a conversational placement, and they will say so before money moves. The company runs setup and management for four to six weeks if the test proceeds. Their review then decides whether to continue. searchads.agency notes that ChatGPT Ads have been live in Austria since 24 August 2026. The agency also notes that DACH benchmarks are still thin. They belong in a comparison with other performance teams, not with content-only GEO studios.
Key Facts
- Best for: Advertisers who already understand search auctions and want a ChatGPT Ads trial
- Core services: ChatGPT Ads evaluation, setup, and management
- Location: Serves Austria and Germany from a search-ads practice

ainomics focuses on how a company is described inside ChatGPT, Perplexity, Google AI Overviews, and Copilot. The agency brands the method as aeo. They start with the current answer, then use persona mapping, prompt sets, owned pages, third-party sources, and monitoring to change that answer. Their priority is whether the description is accurate and commercially usable. The company names healthcare, finance, insurance, tourism, retail, and public-facing organizations as main contexts, especially where a wrong summary creates risk. ainomics is registered at Berggasse in the 9th district. The agency is still new as a GmbH. They should be judged on the partners and the method, not on a long case archive.

Simple AI aims at Vienna service firms that lose inquiries to portals. The agency starts with an audit of Google and AI answers. They then set schema and local signals, then content and internal links, then weekly reports tied to leads. Their local GEO work covers NAP consistency and Vienna-specific questions beside answer-engine structure. The company lists an office at Fleischmarkt in the 1st district. Simple AI publishes lift figures from case-study setups. They should be read as examples of the method. The agency is closer to a neighborhood citation plan than to a multi-country media group.

.kloos keeps technical SEO, content, reputation, and paid search under its GEO, AEO, and LLMO work. The agency treats thin pages, crawl waste, and messy entity data as limits on what ChatGPT or Perplexity can cite. They work from Lindengasse 2/13 in Neubau. Their imprint lists .kloos digital GmbH at that address. The company is small. They operate as a local counterpart, not as a 60-person trading desk. .kloos matches Vienna SMEs that need rankings and AI answers from one team. The agency does not match multi-market paid programs.
Key Facts
- Best for: Vienna SMEs that want SEO and AI search handled by one local team
- Core services: SEO, GEO, AEO, LLMO, content, SEA
- Location: Lindengasse 2/13, 1070 Vienna

komma99 puts local questions such as “Which provider in Vienna should I use?” at the center of GEO. The agency uses a different content and authority plan for national brand questions. They describe structured pages, technical signals, and third-party proof as the levers, not a new keyword sheet. Their stated market is Austria and Germany. The company helps Vienna firms that also sell into Bavaria or other DACH regions in German. komma99 cites a large completed-project volume and strong Google reviews. Those figures describe the broader shop. They do not, by themselves, prove AI-citation outcomes.
Key Facts
- Best for: Austrian and German companies seeking GEO from a Vienna base
- Core services: GEO, local GEO, content and technical optimization for AI search

Advertisery sells GEO in packages: an audit with a 90-day roadmap, a three-month implementation block, then a longer program with authority work. The agency targets citation in ChatGPT, Perplexity, and Google AI Overviews. They list GEO, UX, and PR leads on the public team page. Their plan includes off-site mentions and page experience, not only on-site copy. The company names service firms, agencies, consultancies, and local Vienna businesses as buyers. Advertisery makes a scoped starting package easier to compare than agencies that only attach GEO as a line item under SEO.
Key Facts
- Best for: SMEs that want a scoped GEO package instead of a full media retainer
- Core services: GEO audit, GEO implementation, authority and PR support
- Location: Vienna

Abschluss
ChatGPT changed the job description for marketing in Vienna faster than most briefs admitted. People still Google, but a growing share of shortlists now starts as a question typed into a chat window. That split is the real market. Paid placements under an answer and organic citation inside the answer are different crafts. Mixing them without a measurement plan usually wastes budget.
Location still matters, just not in the old “head office only” way. A Vienna buyer needs someone who understands Austrian search language, local proof, and DACH buying habits. A remote team can do that work if the evidence is there. A local office helps when the questions are hyperlocal. Neither fact, by itself, tells you who will get the brand named correctly.
The useful comparison is practical. Do you need ads in the chat, mentions in the reply, or both? Is the offer a neighborhood service or a B2B product that models already misunderstand? Can the partner show how they track prompts, citations, and actual inquiries, not only traffic? Those answers narrow the field faster than any ranked list.
The channel is still young in Austria. Benchmarks will move. What will not move is the underlying test: when someone in Vienna asks a model for a recommendation, does your company appear, and does the description match what you actually sell? If that sentence is unclear after a first conversation, keep looking.
